Glad you asked! Most people just see the work “lasik” and assume they are the same procedure. There are differences, though, and they are important to be aware of if you’re considering laser vision correction.

Let’s start with a bit of vocabulary. LASIK is an acronym for laser-assisted in situ keratomileusis. All of that means the process of using a laser to create a flap in the cornea and reshape the cornea to return your eyesight to as close to 20/20 as possible.

Vision problems are referred to as aberrations. An aberration is the ophthalmic word for vision problems or visual distortions. Aberrations can be higher order or lower order. Lower order aberrations include astigmatism, near- and farsightedness. Higher order aberrations include night vision problems and seeing halos around lights.

The general consensus is that traditional LASIK is better suited for those with lower order aberrations. Conversely, custom LASIK can treat both higher and lower order aberrations.

Now, let’s talk about the difference in technologies. Traditional LASIK uses your prescription to determine the laser settings used in reshaping your cornea. While it works fairly well, it isn’t always as exact or precise as one would hope. Custom LASIK uses the wavefront technology to map out precise and very predictable laser settings. This technology is so amazing that it allows for corneal reshaping in ultra-minute amounts.

Naturally, this is a very brief overview of the differences between LASIK and custom LASIK. The best thing for you to do, if you’re considering laser vision correction, is to contact an experienced ophthalmologist. You want a LASIK surgeon that has the state-of-the-art equipment, technology and well-trained staff necessary to give you the best results possible.

Sure, you’ve seen the discount ads, but remember. Cutting corners on price may be mean cutting corners on equipment and technology, which may mean cutting corners where your eyesight is concerned. Don’t be stingy when it comes to your vision. Save money on dry cleaning, buying fancy coffee or eating out, instead.
